This is a stumper. Yesterday, I decided to start up my Quicksilver 2002 Dual 1 Ghz with 1.5 mb of RAM, two hard drives and a superdrive. It booted up fine. Today, it won't boot up at all, except on my Tiger DVD disk. But it wouldn't boot from the DVD at first either, because I wasn't able to get the DVD drive open. But I finally did, by opening with Command+Option+O+F and writing "eject CD." (Wonder if I should go back and type, "boot from hard drive." Yeah, it's a joke.) Anyway, when I boot from the Tiger DVD it gets to the point where I can either run Disk Utility or reinstall Tiger, and it freezes. Oh. I did run Command+V, and I get a ton of error messages. Don't know what to do about them, though. Any ideas? Mike PS -- The icon shows my G5. Right now, I have a G5, a G4 and a Mini Mac 2012, my main computer.
